Focusing 1 cycle of 4 sequence points:
Point 1: 1/4th sine wave (angle = 270°)
Point 2: Three sine waves (ratio of frequency to time
is 1:3)
Point 3: Horizontal ramp (f = 0)
Point 4: Falling ramp (f = 0)
3.10.10.1 Loading and saving the arbitrary function
The 99 sequence points of the arbitrary function, which can be manually congured with the control panel of the device and
which are applicable either to voltage (U) or current (I), can be saved to or loaded from a common USB stick via the front side
USB port. Generally, all 99 points are saved or loaded at once using a text le of type CSV which represents a table of values.
In order to load a sequence table for the arbitrary generator, following requirements have to be met:
• The table must contain exactly 99 rows with 8 subsequent values (8 columns) and must not have gaps
• The column separator (semicolon, comma) must be as selected by menu parameter USB logging -> Log le separator
format; it also denes the decimal separator (dot, comma)
• The les must be stored inside a folder called HMI_FILES which has to be in the root of the USB stick
• The le name must always start with WAVE_U or WAVE_I (not case-sensitive)
• All values in every row and column have to be within the specied range (see below)
• The columns in the table have to be in a dened order which must not be changed
Following value ranges are given for use in the table, related to the manual conguration of the arbitrary generator (column
headers like in Excel):
Column Connected to HMI parameter Range
A AC start See table in
“3.10.10. Arbitrary function”
B AC end See table in
“3.10.10. Arbitrary function”
C Start frequency 0...10000 Hz
D End frequency 0...10000 Hz
E Angle 0...35
F DC start See table in
“3.10.10. Arbitrary function”
G DC end See table in
“3.10.10. Arbitrary function”
H Time 100...36.000.000.000 μs (36 billion)
For details about the parameter and the arbitrary function refer to
“3.10.10. Arbitrary function”.
Example CSV:
The example shows that only the rst two sequence points are congured, while all others are set to default values. The table
could be loaded as WAVE_U or WAVE_I when using, for example, the model ELR 10080-1000 4U, because the values would
t both, voltage and current. The le naming, however, is unique. A lter prevents you from loading a WAVE_I le after you
have selected Arbitrary --> U in the function generator menu. The le would not be listed at all.
